This won't help this time but it might be useful for any future house moves you make:
The root of your problem lies in that dreaded word 'solicitors'. In future, seek out the services of an independent licensed conveyancer. The firm I used had a rule that they would always phone me within one hour of receiving any fax or letter from the other person's solicitor, to discuss the contents. They also agreed that, assuming they could get a response from me, they would always get a reply off within two hours and immediately put a copy of the original communication, together with a copy of their reply, in the post. They kept to their promises. When the other person's solicitor starting delaying things, they sent him daily faxes and repeatedly phoned him. A copy of every fax and a log showing the date and time of every call was always promptly posted to me. As a result, the whole thing was sorted out very quickly.
Incidentally, unlike solicitors (who often charge for every letter or phone call), this was all done for a flat fee which was arounf one third of what a solicitor mighthave charged.
Moral: Avoid solicitors!
